What are the thread limits for the Dispatchers.IO dispatcher in coroutines?

The Kotlin coroutine dispatcher Dispatchers.IO is intended for input-output operations and uses a thread pool, the size of which by default is 64 threads or the number of processor cores if it is greater. This limit is introduced to prevent excessive thread creation, which can lead to performance degradation due to context switching. Therefore, the maximum number of threads in Dispatchers.IO is usually limited to 64.
